Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a device for removing foreign bodies from the gastrointestinal tract. Background Technology

[0002] Many patients frequently ingest various foreign objects, especially children who have poorer gag reflexes and incomplete molars, making them more prone to swallowing foreign objects. When a patient accidentally swallows a foreign object, it is usually removed from the patient's gastrointestinal tract using foreign body forceps.

[0003] To determine the size of the foreign object, a CT scan is performed on the patient first. However, the material of the foreign object cannot be observed from the CT images alone. Doctors can only rely on experience to select a foreign body forceps for surgery. If the surface of the foreign object is very smooth, a mesh-type foreign body forceps must be used, which prolongs the operation time, increases the patient's pain, and is not conducive to the patient's treatment. Furthermore, the existing foreign body forceps require the doctor to operate them with their hands suspended in the air. Prolonged surgery will cause wrist fatigue, which in turn affects the doctor's ability to operate the foreign body forceps. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a gastrointestinal foreign body removal device, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a gastrointestinal foreign body removal device, including a flexible tube, a foreign body forceps assembly and a control assembly. The foreign body forceps assembly is disposed on the flexible tube, the control assembly is disposed on the top of the flexible tube, and the control assembly is connected to the foreign body forceps assembly.

[0006] The bottom of the flexible hose is the bend end of the hose, and the top of the flexible hose is the top of the hose. Inside the flexible hose, the bend end of the hose is provided with a clamp head groove, and the sides of the clamp head groove are provided with clamp head limiting grooves. The top of the hose is provided with a bend adjustment chamber and a cable groove. The top side wall of the hose is provided with a control groove and a platform thread, and the platform thread is located below the control groove.

[0007] Furthermore, the top of the control slide is provided with a spring sleeve slide groove, the upper part of the spring sleeve slide groove is provided with a vent hole, the side wall of the platform thread is provided with a platform limiting groove, the bottom of the platform thread is provided with a platform limiting boss, the flexible hose is provided with an internal basic component, the internal basic component includes an objective lens cable, a water spray pipe, an optical fiber and a bending adjustment rope, the objective lens cable, the water spray pipe and the optical fiber are connected in the cable groove, and the bending adjustment rope is connected in the bending adjustment chamber.

[0008] Preferably, light is provided by optical fiber, the objective lens on the objective lens cable transmits the condition inside the patient's body to the display, and the water spray tube sprays or draws in liquid to prevent digestive fluids inside the patient from obscuring the objective lens.

[0009] Furthermore, the foreign object clamp assembly includes a double-sided clamp and a net-shaped foreign object rod. The net-shaped foreign object rod is located inside the double-sided clamp. The double-sided clamp includes a clamp head seat and clamps. The clamps are symmetrically arranged on the clamp head seat, and the clamp head seat slides within the clamp head groove.

[0010] Furthermore, the clamp head seat is provided with symmetrical limiting bosses on both sides, the limiting bosses slide in the clamp head limiting groove, the bottom of the clamp head limiting groove is provided with a square sliding groove, the lower side of the square sliding groove is provided with a clamping groove, the clamping groove is provided with a push rod baffle and a clamping rotating column, the top of the clamp head seat is provided with a lifting tube, the top of the lifting tube is provided with a lifting tube top plate, and the lifting tube top plate slides in the control sliding groove.

[0011] Furthermore, the clamp is provided with a clamp rotation groove, the clamp rotation column is provided in the clamp rotation groove, the clamp is also provided with a clamp control groove, and a net pocket limiting groove is provided at the center of the clamp head.

[0012] Furthermore, the bottom of the net-shaped foreign object rod is provided with a net, the top of the net-shaped foreign object rod is provided with a spring sleeve and a spring, the spring sleeve slides in the spring sleeve groove, the spring is located in the spring sleeve, and the bottom of the side wall of the spring sleeve is provided with a lower pressure plate, which slides in the control groove.

[0013] Preferably, when the surface of the foreign object in the patient's body is relatively smooth, such as a glass marble, the doctor presses down the pressure plate with their finger, causing the net at the bottom of the foreign object sling to slide out of the net foreign object sling hole of the clamping control rod, thus retrieving the glass marble from the patient's body. After the finger stops pressing down the pressure plate, the spring drives the net foreign object sling to return to its original position, and the net slides into the net foreign object sling hole, thereby tightening the net. At the same time, the clamp is closed, and the clamping net limiting groove squeezes the net, preventing the glass marble from slipping out of the net during the process of removing the foreign object from the patient's body.

[0014] Furthermore, the control assembly includes a clamping control lever and a control ring. The clamping control lever is located inside the lifting tube, and the control ring is located on the control slide groove. The control ring has an inner wall thread and an annular groove inside. The side wall of the threaded plate has threads, and the side wall of the threaded plate is connected to the inner wall thread by threads. The top plate of the lifting tube is located in the annular groove.

[0015] Furthermore, the bottom of the clamping control lever is provided with a square boss, and clamping drive columns are symmetrically arranged in the groove of the square boss. The square boss slides in the square slide groove, and the clamping drive columns are arranged in the clamping control groove. The top of the clamping control lever is provided with a threaded plate fixing shaft. The center of the clamping control lever is provided with a net bag foreign object clamping sliding hole, and the net bag foreign object rod is arranged in the net bag foreign object clamping sliding hole. The threaded plate is arranged on the threaded plate fixing shaft.

[0016] Preferably, the doctor moves the control ring up and down with their finger, which moves the lifting tube and the clamp control lever, thereby causing the clamp head seat and clamps of the double-sided foreign body clamp to retract or extend from the clamp head slide groove. When the doctor rotates the control ring, the inner thread slides across the side wall of the threaded plate, causing the threaded plate to move up and down, which in turn causes the clamp control lever to move up and down. The clamp drive column at the bottom of the clamp control lever controls the opening and closing of the two clamps, thus enabling the removal of foreign objects from the patient's body.

[0017] Furthermore, the control assembly also includes a bending adjustment assembly, a hand placement platform, and a threaded plate. The bending adjustment assembly is located inside the bending adjustment chamber. The hand placement platform is located on the platform thread and slides on the platform limit groove. The bottom of the hand placement platform is provided with a threaded rotating sleeve, which is rotatably connected to the hand placement platform. The threaded rotating sleeve is connected to the platform thread via a thread.

[0018] Preferably, the surgeon can place his palm on the hand placement platform during surgery to prevent wrist fatigue caused by prolonged hand suspension during surgery. In addition, since different surgeons have different palm sizes, the height of the hand placement platform can be adjusted by rotating the threaded rotating sleeve.

[0019] Furthermore, the bending adjustment assembly includes an adjustment rod and a damping bushing. The two adjustment rods are arranged crosswise in the bending adjustment chamber. The damping bushing is connected between the two adjustment rods. Rope posts are provided on both sides of the adjustment rod. An adjustment knob is provided at one end of the adjustment rod. The bending adjustment rope is wound on the rope post. The bending adjustment ropes on the rope posts on both sides of the same adjustment rod are wound in opposite directions.

[0020] Preferably, since the bending adjustment ropes on the rope posts on both sides of the same adjustment rod are wound in opposite directions, when the adjustment knob is turned, the rope post at one end of the same adjustment rod will release the bending adjustment rope, while the other rope post will rewind the bending adjustment rope. This causes the bent end of the hose to bend toward the side where the bending adjustment rope is wound. By rotating the two adjustment knobs to adjust the bending of the bent end of the hose, the patient's gastrointestinal tract can be better observed, facilitating the removal of foreign objects.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows:

[0022] 1. Light is provided through optical fibers, and the objective lens on the objective lens cable transmits the condition inside the patient's body to the monitor. The water spray tube sprays or draws in liquid to prevent digestive fluids inside the patient from blocking the objective lens.

[0023] 2. When the surface of the foreign object in the patient's body is relatively smooth, such as a glass marble, the doctor presses down on the pressure plate with their finger, causing the mesh at the bottom of the foreign object sling to slide out of the mesh foreign object forceps sliding hole on the clamping control lever, thus retrieving the glass marble from the patient's body. After the finger stops pressing down on the pressure plate, the spring drives the mesh foreign object sling back to its original position, and the mesh slides into the mesh foreign object forceps sliding hole, thereby tightening the mesh. At the same time, the clamp is closed, and the mesh limiting groove of the clamp squeezes the mesh, preventing the glass marble from slipping out of the mesh during the process of removing the foreign object from the patient's body.

[0024] 3. The doctor moves the control ring up and down with his finger, which moves the lifting tube and the clamp control lever. This causes the clamp head seats and clamps of the double-sided foreign body clamps to retract or extend from the clamp head slide groove. The doctor rotates the control ring with his finger. During the rotation of the control ring, the inner thread slides across the side wall of the threaded plate, causing the threaded plate to move up and down, which in turn causes the clamp control lever to move up and down. In turn, the clamp drive column at the bottom of the clamp control lever controls the opening and closing of the two clamps, thus realizing the removal of foreign objects from the patient's body.

[0025] 4. During surgery, doctors can place their palms on the hand placement platform to prevent wrist fatigue caused by prolonged hand suspension during surgery. In addition, different doctors have different palm sizes, and the height of the hand placement platform can be adjusted by rotating the threaded rotating sleeve.

[0026] 5. Since the bending adjustment ropes on the rope posts on both sides of the same adjustment rod are wound in opposite directions, turning the adjustment knob will cause the rope post at one end of the same adjustment rod to release the bending adjustment rope, while the other rope post will rewind the bending adjustment rope. This will cause the bent end of the hose to bend toward the side where the bending adjustment rope is wound. By turning the two adjustment knobs to adjust the bending of the bent end of the hose, it is possible to better observe the inside of the patient's stomach and intestines, making it easier to remove foreign objects.

The top of the lifting tube 2114 has a lifting tube top plate 2117. The lifting tube top plate 2117 slides in the control sliding groove 122.

[0049] The clamp 212 is provided with a clamp rotation groove 2121, the clamp rotation column 2116 is provided in the clamp rotation groove 2121, the clamp 212 is also provided with a clamp control groove 2122, and the head center of the clamp 212 is provided with a net pocket limiting groove 2123.

[0050] The bottom of the net bag foreign object rod 22 is provided with a net bag 221, and the top of the net bag foreign object rod 22 is provided with a spring sleeve 222 and a spring 223. The spring sleeve 222 slides in the spring sleeve groove 1221, and the spring 223 is located in the spring sleeve 222. The bottom of the side wall of the spring sleeve 222 is provided with a lower pressure plate 2221, and the lower pressure plate 2221 slides in the control groove 122.

[0051] The control assembly 3 includes a clamping control lever 31 and a control ring 32. The clamping control lever 31 is located inside the lifting tube 2114, and the control ring 32 is located on the control slide 122. The control ring 32 has an inner wall thread 321 and an annular groove 322 inside. The side wall of the threaded plate 35 is threaded, and the side wall of the threaded plate 35 is connected to the inner wall thread 321 by threads. The top plate 2117 of the lifting tube is located inside the annular groove 322.

[0052] The clamp control lever 31 has a square boss 311 at the bottom, and clamp drive posts 3111 are symmetrically arranged in the groove of the square boss 311. The square boss 311 slides in the square slide groove 2112. The clamp drive posts 3111 are located in the clamp control groove 2122. The clamp control lever 31 has a threaded plate fixing shaft 312 at the top. The clamp control lever 31 has a net bag foreign object clamp sliding hole 313 at the center. The net bag foreign object rod 22 is located in the net bag foreign object clamp sliding hole 313. The threaded plate 35 is located on the threaded plate fixing shaft 312.

[0053] The control component 3 also includes a bending adjustment component 33, a hand placement platform 34, and a threaded plate 35. The bending adjustment component 33 is located inside the bending adjustment chamber 121. The hand placement platform 34 is located on the platform thread 123 and slides on the platform limit groove 1231. The bottom of the hand placement platform 34 is provided with a threaded rotating sleeve 341, which is rotatably connected to the hand placement platform 34. The threaded rotating sleeve 341 is threadedly connected to the platform thread 123.

[0054] The bending adjustment assembly 33 includes an adjustment rod 331 and a damping bushing 332. The two adjustment rods 331 are arranged crosswise in the bending adjustment chamber 121. The damping bushing 332 is connected between the two adjustment rods 331. Rope posts 3311 are provided on both sides of the adjustment rod 331. An adjustment knob 3312 is provided at one end of the adjustment rod 331. The bending adjustment rope 134 is wound on the rope post 3311. The bending adjustment rope 134 on the rope posts 3311 on both sides of the same adjustment rod 331 is wound in opposite directions.

[0055] In practical use, the bent end 11 of the flexible tube is inserted into the patient's stomach and intestines. The inside of the patient's stomach and intestines is observed through the objective lens at the front end of the objective lens cable 131. At the same time, the adjustment knob 3312 is rotated. The bending adjustment rope 134 is wound in opposite directions on the rope post 3311 of the same adjustment rod 331. When the adjustment knobs 3312 on both sides drive the adjustment rod 331 to rotate, the rope post 3311 at one end of the same adjustment rod 331 will release the bending adjustment rope 134, while the other rope post 3311 will wind up the bending adjustment rope 134. This causes the bent end 11 of the flexible tube to bend towards the side where the bending adjustment rope 134 is wound. By rotating the two adjustment knobs 3312 to adjust the bending of the bent end 11 of the flexible tube, the inside of the patient's stomach and intestines can be observed better, making it easier to remove foreign objects.

[0056] During the removal of the foreign object, the doctor adjusts the height of the hand placement platform 34 by rotating the threaded rotating sleeve 341 according to the size of the hand. The doctor places the hand on the hand placement platform 34, grasps the top 12 of the flexible tube, and pinches the control ring 32 with their fingers, causing the control ring 32 to move downward within the control groove 122. The annular groove 322 of the control ring 32 pushes the top plate 2117 of the lifting tube downward, and the inner wall thread 321 causes the threaded plate 35 to move downward, which in turn causes the lifting tube 2114 and the clamp control lever 31 to move downward, that is, the clamp head seat 211 moves downward. The clamp head seat 211 moves downward from the clamp head groove 11 on the bent end 11 of the flexible tube. 1. Slide out and rotate the control ring 32. During the rotation of the control ring 32, the inner wall thread 321 slides across the side wall of the threaded plate 35, causing the threaded plate 35 to move up and down. The threaded plate 35 causes the clamp control rod 31 to move up and down. The square boss 311 at the bottom of the clamp control rod 31 slides in the square slide groove 2112 of the clamp head seat 211. The clamp drive column 3111 slides in the clamp control groove 2122. During the up and down movement of the clamp drive column 3111, the clamp 212 rotates around the clamp rotation column 2116, thereby controlling the opening and closing of the two clamps 212 to achieve the removal of foreign objects from the patient's body.

[0057] During the movement of the clamping control lever 31, the net foreign body rod 22, under the elastic force of the top spring 223, maintains the lower pressure plate 2221 of the spring sleeve 222 against the top of the control slide 122. When the surface of the foreign body in the patient's body is relatively smooth, such as a glass marble, the double-sided clamp foreign body clamp 21 has difficulty in stably clamping the glass marble. Adjust the clamp 212 to the fully open state, press the lower pressure plate 2221 with your finger, and the spring sleeve 222 drives the net foreign body rod 22 to move down. Then, the net 221 at the bottom of the net foreign body rod 22 moves out of the net foreign body clamp sliding hole 3 of the clamping control lever 31. The glass marble is scooped out of the patient's body by the net 221. After the finger stops pressing down on the pressure plate 2221, the spring 223 pushes the spring sleeve 222 upward, and the net 221 slides into the sliding hole 313 of the net foreign body forceps. Then the net 221 tightens. Because the net 221 contains a foreign object, the net 221 cannot be completely put into the sliding hole 313 of the net foreign body forceps. The clamp 212 is closed. The clamp 212 squeezes the net 221 by the net limiting groove 2123 to prevent the glass marble from slipping out of the net 221 during the process of removing the foreign object from the patient's body.
